In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign.
The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.

its not much different besides the fact it has a '<' or a '>' insted of a '='. and you have to add/subtract/etc. a little diffrent.
When you divide both sides by a negative value
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").
It is called the DOMAIN!
The difference between them is that when solving an "and" inequality you are comparing two inequalities and when you are solving an "or" inequality you dont compare, you only use one inequality example of "and" . 2<x+3<7 example of "or" . 4<d or m<1
